The Russian October Revolution of November 1917

Red Square, Moscow (Russia)

The October Revolution (Russian: Октябрьская революция, Oktyabr'skaya revolyutsiya), also known as the Great October Socialist Revolution, Red October or the Bolshevik Revolution, was a political revolution and a part of the Russian Revolution of 1917. It took place with an armed insurrection in Petrograd traditionally dated to 25 October 1917 Old Style (O.S.), which corresponds to 7 November 1917 New Style (N.S.).

It followed and capitalized on the February Revolution of the same year. The October Revolution in Petrograd overthrew the Russian Provisional Government and gave the power to the local soviets dominated by Bolsheviks. As the revolution was not universally recognized outside of Petrograd there followed the struggles of the Russian Civil War (1917–1922) and the creation of the Soviet Union in 1922.
The revolution was led by the Bolsheviks, who used their influence in the Petrograd Soviet to organize the armed forces. Bolshevik Red Guards forces under the Military Revolutionary Committee began the takeover of government buildings on 24 October 1917 (O.S.). The following day the Winter Palace (the seat of the Provisional government located in Petrograd, then capital of Russia), was captured.
